What makes this tool more useful

Compare a 50/50 constant-product liquidity position with simply holding both assets after their relative price changes.

How the calculation works

For a 50/50 constant-product pool, relative LP value is two times the square root of the price ratio divided by one plus that ratio. Loss is measured against holding.

Stress-test a simplified Uniswap v2-style position. Concentrated liquidity and non-50/50 pools require different models.

Important financial information

This calculator provides an educational estimate from the values you enter. It does not use live prices, predict returns or provide investment, tax or legal advice. Verify exchange rules, fees, rates and product terms before making a financial decision.

Private, fast and mobile-ready

The workspace runs with browser JavaScript and does not submit entered values to a Rantey calculation endpoint. Controls use readable labels, large touch targets and responsive result panels for narrow screens.
